[目的]为阐明混合接种蚯蚓及植物促生根际细菌技术在蔬菜生产中的作用。[方法]采用室内盆栽试验的方法,研究接种蚯蚓、植物促生根际细菌(固氮细菌和钾活化细菌)对甘蓝生长的影响以及甘蓝对氮和钾的吸收。[结果]7种接种方式均明显促进了甘蓝根上部分的生长,其中混合接种蚯蚓、固氮细菌和钾活化细菌处理下甘蓝根上部分生物量最大。5种接种方式(接种蚯蚓、双接蚯蚓和固氮细菌、双接蚯蚓和钾活化细菌、双接钾活化细菌和固氮细菌以及混合接种)下甘蓝地上部分氮的吸收量在0.05水平显著高于对照。[结论]混合接种方式是一种有潜力的生物技术,可以用来减少蔬菜生产中化肥的施用量。
[Objective] The research aimed to clarify the effect of mixed inoculation of earthworm and plant growth-promoting rhizobacteria on vegetable production. [Method] The effects of earthworm inoculation, plant growth rhizobacteria (nitrogen-fixing bacteria and potassium-activated bacteria) on the growth of cabbage and the absorption of nitrogen and potassium in cabbage were studied by pot experiment. [Result] The 7 kinds of inoculation ways obviously promoted the growth of the upper part of cabbage root. The mixed biomass of earthworm, nitrogen - fixing bacteria and potassium - activated bacteria had the highest biomass. Under five kinds of inoculation methods (earthworm inoculation, double earthworm and nitrogen-fixing bacteria, double earthworm and potassium-activated bacteria, double potassium-activated bacteria and nitrogen-fixing bacteria and mixed inoculation), the uptake of aboveground nitrogen in cabbage was significantly higher than that of the control . [Conclusion] The mixed inoculation method is a potential biotechnology that can be used to reduce the amount of chemical fertilizer used in vegetable production.
